Abstract (en)
[origin: WO2012175888A1] The present invention relates to the generation of map data. A measurement instrument, i.e. a mobile body, measures distances between a current position of the mobile body and obstacles in the environment of the mobile body. The invention comprises, in particular: a) taking at least N measurements of distances between the mobile body and obstacles in said environment, by consecutive angular steps of A/N each, in which A is a predetermined angular sector at least partially defining said environment of the mobile body, and combining said distances with the respective angular steps in a working memory, in order to establish map data; b) moving the mobile body and repeating step a) for a new current position of the mobile body; and c) simultaneously determining, according to the distances measured for each angular step of the current position of step b) and the preceding position of step a), the current position of the mobile body in step b) on said map relative to the initial position thereof in step a), and new data of said map.
